Summary
Daily rhythms in energy needs and cardiovascular function are controlled by internal biological clocks. This review explores how circadian clocks orchestrate metabolism to support cardiovascular health and disease.
Area of Science:
- Physiology
- Chronobiology
- Metabolic Science
Background:
- Daily fluctuations in energy supply and demand align with sleep-wake and feeding cycles.
- Cardiovascular parameters like blood pressure and heart rate exhibit 24-hour rhythms.
- Metabolic processes oscillate to meet daily cellular needs for energy and signaling molecules.
Purpose of the Study:
- To review the circadian regulation of metabolism.
- To examine the synchronization of metabolic rhythms with cardiovascular function.
- To investigate the role of circadian metabolic disruption in cardiovascular disease pathogenesis.
Main Methods:
- Literature review of current knowledge on circadian clocks and metabolism.
- Analysis of mechanisms linking metabolic rhythms to cardiovascular function.
- Discussion of evidence for circadian misalignment in cardiovascular disease.
Main Results:
- Cardiovascular cells utilize autonomous circadian clocks for anticipatory metabolic orchestration.
- Metabolic pathways are temporally regulated by internal clocks to meet predicted physiological demands.
- Circadian clocks coordinate metabolic processes with cardiovascular rhythms.
Conclusions:
- Circadian clocks play a crucial role in synchronizing metabolism with cardiovascular function.
- Disruption of metabolic circadian rhythms may contribute to cardiovascular disease development.
- Understanding these mechanisms is vital for cardiovascular health.

02:19Circadian Rhythms and Gene Regulation
4.1K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:31Regulation of Heart Rates
1.8K
The regulation of heart rate is a complex process controlled by the autonomic nervous system (ANS), hormonal influences, and intrinsic cardiac mechanisms. The ANS has two main components: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

The regulation of the cardiovascular system allows the body to adapt to various demands and maintain homeostasis.
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...

01:30Factors Influencing Heart Rate
2.6K
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
